Abstract:

In this study, heavy metal/trace element accumulation was investigated in soils along the
road passing through Gümüshane city center and shoots of 1-2 years of acacia trees
(Robiniapseudoacacia L.) grown in these soils. Heavy metal contents in soils and plants
were analyzed by Enrichment Factor (EF), Geo-accumulation index (Igeo) parameters,
and by Bio Accumulation Factor (BAF), respectively. According to geo-accumulation
index (Igeo) data, it is seen that the soil was unpolluted in terms of Cr, Co, Cu, Rb, Sr;
unpolluted to moderately polluted in terms of V, Ni and Zn; moderate to excessively
polluted in terms of As, and moderate to excessively polluted in terms of Pb. According to
EF parameters, on the other hand, it is observed that the soil was non to slightly enriched
in terms of Cr, Co, Sr and Ba; non to moderately enriched in terms of Ni and Cu; slightly
to significantly enriched in terms of Zn; significant to very highly enriched in terms of As
and slightly to over excessively enriched in terms of Pb. Although trace/heavy metal
contents of acacia shoots were usually within normal values for acacia, it was determined
that Cu, Fe, Mo, Ni, Sr and Zn concentrations were within and/or above upper limits of
normal values in certain sampling points.
